How to enable treble support in old devices?

Today, I am back to challenge you all. As you would have guessed from the question title, this post is to know about enabling treble support on old phones. Of course, there are a lot of guides on the internet about this and I **"will"** explain how this post is different from them. First, we have a post about this on this very site. Link: Here, the question has not been properly answered so this is not helpful. I found the next link from the above link. Link: This is specific to redmi note 4. So, provides no help to non MIUI users. Now, we can definitely install a custom rom to enable treble but such roms are not available for all devices. So, now, let me be specific with my device. I have a device running Android 5.1 with MediaTek MT6735 processor. Now, I have searched a lot in the internet about custom roms and have installed many roms and have **"many times hard bricked my phone"**. With no options left with me and you not annoyed by reading so much, can you please give me a way I can enable treble support using a similar way found in the above XDA post? Or any other way, if you know? And please don't, just don't tell me to either buy a new phone or give up trying to enable treble support on my device. Thanks for reading.
